Merrimac Residents
If you heat with natural gas, you are eligible for a no-cost Mass Save® Home Energy Assessment.
Make your home more comfortable, reduce energy use, and save money.
Merrimac Municipal Light Department is helping residents reduce energy usage, improve home comfort, and save on costs. The Town of Merrimac Light is partnering with HomeWorks Energy, a trusted Mass Save partner, to assist residents with natural gas in making their homes more efficient, starting with a no-cost Home Energy Assessment.
Beginning in February of 2025, HomeWorks Energy representatives will visit neighborhoods to invite homeowners and renters to schedule a no-cost assessment. During an assessment, a Home Energy Specialist reviews a home’s energy performance and shows the homeowner how to save money and energy year-round.
